Application filed March 19, 1910. Serial No.- 550,337.

To all whom it may concern:

Be it known that I, DANIEL M. MCLAUGH- LIN, a citizen of the UnitedStates, residing at Louisville, in the county of J efierson and State ofKentucky, have invented certain new and useful Improvements in HeatingSystems; and I do hereby declare the fol lowing to be a full, clear, andexact description of the invention, such as'will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in heat-ing systems, and has foran object to provide a system of pipes, in combination with a heater,the pipes having valves for automatically opening against the pressureof the Water therein, when a portion of the water has been heated toproduce a higher pressure against one sideot' the valves, than existsupon the other side.

A iurtherobject of the invention is to provide in a heating system, aheater adapted to be connected with a flame for heating water passingthrough saidsystem and said heater.

A further object of the invention is to provide in a heating system,aheater adapted to be moved into and out of engagement with a flameburning adjacent the heater.

A further object of the invention is to provide in a heating system, incombination with a device for transmitting heat, a heater for heatingwater passing through said system and said heater. I

A further object of the invention is to provide in a heating system, aheater pivotally mounted, to be operatedinto and out of contact with aflame for heating water passing through said heater.

' A further object of the invention is to provide in a heating system,in combination with a heater, means for operating the heater into andout of contact with a heating medium.

A further object of the invention is to provide in a heating system, aheater adjustably mounted for the purpose of varying the position of theheater, to permit the same to be heated by a device for transmittingheat thereto. Y A further object 'ofthe inventionis to provide in aheating system, in combination with a heater, 'a-flexible water-tightoint, through which water may be conveyed to the beaten;-

A objectoftheinventionis to,

providein a heating system, in combination with a heater, a rotatablewater-tight joint to prevent the leaking of water passing through thejoint to or from the heater.

A further object of the invention is to provide in a heating system, incombina tion with individual heaters, coil pipes connected with theheaters to receive-and trans: mit water from one heater to the other,the coils being soarranged as to be simultaneously heated with theheaters, for increasing the heat of the water passing therethrough. I I

"A further object of the invention is to provide in a heating system, incombination with a heater, a frictional'water-tight rotatable joint,between said systemand said heater, whereby the friction between partsof said joint acts to retard the movement of said heater from a verticalto a horizontal.

and valves located therein, with the heaters I v in a raised position.Fig. 2 represents a side elevation of the heater in a raised position,and showing, by dotted lines, the horizontalposition of the heater inconnection with the. top of a range. Fig. 3 represents an enlargedbottom plan v ew of the heaters, showing the manner of attaching thecoils thereto and connecting the heaters to-' gether'. Figs 4 is asection. through the heaters, taken on lines A B of Fig. 3.

Fig. 5 is an enlarged detailed sectionalview of the rotatablewater-tight joint shown in duplicate in Fig. 1.

This invention is intended to be appli} cable to stoves, gas ranges,electric heaters v or any fuel burning device, for heating water forhousehold or other purposes. The

device as shown, is placed behind 'a gas range, out of the way when notin use, and

by means of the rotatable water-tight-j'oint it may be brought intoposition, as shown by dotted'lines in Fig. 2, to be heated'by a -fiamefrom the-range. i

-Referring to the drawings by numerals, 1

. represents a water pipe adapted to be:con-

the pipe 1 is a pair of Ts, as at 2, which are l connected with shortupright pipes 3, which in turn. are connected with a pair of Us, as

at l. Mounted on the pipe 1 between the Ts 2 is a valve casing 5, inwhich is situated a flap valve 6, positioned to force water,

through the first upright'pipe 3 and thence through the heaters to thefaucet. A short connecting pipe 7 is secured to the left hand member 4which connects-with one end of a valve casing 8, in which is seated aflap valvefi, positioned to allow water to pass to the heaters 10, butto prevent its returning therefrom. The other end of the valve casing 8is connected with a short pipe 11, and

. a corresponding short pipe 12 is connected to the right hand member 4.Between the pipes 11 and 12 the parts of the mechanism are duplicated oneach side of the centrally closed pipe 13, and adescription of one setof. the parts will be sutficient for both, the

same numerals applying to each. Connected tothe pipes 11 and 12 are apair of watertight rotatable joints 14; The rotatable water-tight joints14 consist of a union nut 15 securing a rigid joint-connection 16 infrictional engagement with a rotatable reducing-connection 17. Theunion-nut 15 is made rigid with thereducingconnection 17 by beingscrewed upon same, but is left free to turn upon the rigid connection16, in frietional engagement therewith. Thenut 15 is held upon'the rigidconnection 16 by means of a flange-18 carried by the connection, whchengages the inner flange of the nut. The rigid connection 16 is providedwith a hollow stem 19, which is threaded. externally on. its outer end.An openpacking nut 21, threaded internally to receive the end of thehollow stem 19, is adapted to adjustably engage and position apacking'ring 22 ,bearing against packing 23 positioned aroundthe hollowstem 19 and contained in a hollow pipe 24, connectin the T 25 with thereducing-connection 1 The pipe 24 1s screwed into one end of the T 25,in which is positioned the end of the stem 19 and the packing nut 21located thereon. A ground.

joint is formed between the packing nut 21 and the packingring 22 toprevent the back passage of water between the ring and the nut. In theopposite end of the T 25, is screwed the central pipe 13, with apartition 26 located therein, to force water from the 'hollow stem 1.9upthrough the pipe 27, con

necting theT 25 and one of the heaters 10. The pipe 27g isthreadedexternally at both ends tor-screwainto the heater and the T,

while a. similar pi p'e 2 8 is threaded externally at the bottom end toscrew into. the other T 25, and intermilly at the top end to receive anexternally threaded coil pipe 29. The coil pi i 29 is made the same inboth heaters and is scre\vcd in'to-an opening 30 a manner as to allowthe flame from the tom of the heater and simultaneously at the sameangle upon the coil. The coils 29 are also spaced a short distance fromthe bottom of the heater, to furnish an air chamber for the bettercombustion of the gases 1 around the heating sail-faces of the eoils'andheaters.

Any back radiation of heat from the bottom walls of the heaters willstrike the coils and tend to increase the heat of the water passingtherethrough. The heaters are provided with water heating chambers 31,with which are connected the coil pipes 29. The two heaters areconnected by a cross. pipe 32, one end of which is threaded externally,to screw intoone of the heaters and the other threaded internally toreceive the outer CX- ternally threaded end of the coil from theopposite heater. The pipe 32 serves as a brace and tie between the twoheaters, as well as a means for ctuii eving water from one of theheaters to the'lfother. A concave opening 33 is cut in the bottomcircular wall of the heaters to receive the coil pipes 29,

the outside diameter of the connecting pipes 28 and 32L to provide ashoulder or seat for the ends of the two connecting pipes, which bearagainst the outer peripheries of the walls of the heaters. A dischargepipe 34 is provided, having a valve 35'loratcd therein, which is oerated by a handle 36 for discharging 01: or cold water from and throughthe heaters, as desired. I K

In order to provide means for moving the heaters into and out ofengagement with the burners of the as range, a handle 37, (shown only inl l and 2) of some nonheat-conducting material, is mounted on a bolt orshaft 3S,-passing through an upturned eye, carried by each of the handlesupports 39, with opposite ends turned at right angles to the main bodyof the support and screwed into the walls of the heat.- ers, for thehandle.

In my improved device, when it is desired to heat a quantity ofwaler,-the heatersare lowered by the rotation of the movable parts ofthe water-tight joint upon the rigid. parts thereof, to a positionimmediately over the burners ol the gas range-and the burners then beinglighted, or previously having been lighted, permit the flames to conicin positioned thereunder. and by opening the valve 35, hot water willbegin to How from the discharge pipe 34 and will continue to do so, aslong as the QHSd't'flltllHS burning in contact with the heaters.

burner. to play at a right angle to the botthe openings being smaller indian'ieterthanpurpose of supporting the if direct contact with theheaters and the coils,

The object of the flap valve 6 is to act, in part, as a safety valve, sothat in case the valve 351s left closed and the pressure of means forpivotally connecting the heater with the hot and cold Water pipeswhereby the heater may be movedinto and out of the water in the heaters,by reason of being a engagement with a'fixed heating'mtidium.

2. In a heating system, a heater, 2. cold' heated, becomes greater thantheinitial pressure of the water in the pipe leading to the heaters, thedanger of an explosion may be avoided, by the flowing of the heatedwater, or steam, through the pipe 1 to the back face of the flap valve6, to raise the valve i and allow the pressure to equalize on both sidesthereof. Likewise the flap valve 9 being set in the opposite directionto the valve i 6, will prevent cold water from passing back i intotheentrance pipes leading from the mam. But as long as valve 35 is open andwater is being heated, the initial pressure of the cold water in theentrance pipes will E raise the valve 9 and allow the water to flowthrough the heaters to the discharge pipe However the valve does nothave to be opened in order for the cold water in the pipes leading tothe heater to flow through the heaters, the pipes will raise the valve9, regardless of whether the valve is open or not.

hack to the heaters. through the cool water as the pressure of the waterin i l i supply side of said heaters. This circulation of water iscaused by the displacement of the heated water in the heaters low-10 andit is caused to move in this direction by the position of the valvemembers (i and 9 which do not materially resist such circulation, but

will prevent any reverse circulation.

While the device herein described is shown in connection with a'gasrange, it will be obvious that itcould equally as well be applied toother heating mediums.

\Vhat I claim is- 1. In a heating system, a heater, a cold water pipeleading to the heater, a check valve positioned in the pipe and adaptedto permit the tlow of water to the heater, a hot water pipe leading fromthe heater, a valve interposed in the hot water pipe, a by-pass pipeconnecting the hot water pipe with the k short eu-cmtmg the E cold waterpipe for water from the hot water pipe to the cold water pipe when thevalv in the hot water pipcis closed, a check valve positioned in theby-pass pipe and adapted to permit hot watcr to flow into the cold waterpipe, and.

i neeting If valve is closed the water will c1r-' E from the ing thewater from the hot water pipe to the cold water pipe when the valve inthe hot water pipe is closed, a check valve positioned in the by-passpipe and adapted to permit hot water to flow into the cold water pipe,and a rotatable frictional joint connecting the heater to thehot andcold Water pipes whereby the friction of the joint serves to retard themovement of the heater from a substantially verticalrposition downward.

3. In a heating system, a heater, an entrance pipe to the heater, adischarge pipe from the heater, means for pivotally conthe'heater withthe pipes, a water heating chamber carried by the heater, a coil pipeconnected with the chamber and spaced from and adjacent the heater andconnected with adischarge pipe, whereby water passing through the heaterand the coil pipe may be heated simultaneously and dlscharged from theheater, and means for automat1 ca-l ly equalizing the pressure of thehot Water heater with the water in ,the cold water pipes.

4. In a heating system, a'heater, an entrance pipe to the heater, adischarge pipe from the hea er, means for pivotally connectingthe'heater with the pipes, a water heating chamber carried by theheater. a coil pipe connected with the chamber and spaced from andadjacent the heater and connected with the discharge pipe, whereby waterpassing through the heater and the coil pipe may be heatedsimultaneously and discharged from the heater.

In testimony whereof I atlix my signature in presence of two witnesses.
